How to refresh to a specific version?

How to refresh to a specific version?

[Hartmut Goebel]

Hi,

guix refresh fetches the newest version of packages. How can I refresh
to a specific version or to the newest sub-version of a specific minor
version?

Rational: Qt has released 5.10, while 5.9 is still maintained. I want to
refresh to the latest 5.9.x version, but not (yet) to 5.10, as the later
might require bigger changes.

That’d be useful but it’s currently not supported.

I think one way to do that would be to add a property in packages that
would instruct updaters to restrict the version search space to a given
regexp.
